For the great stream a bulwark meet
That laves its rock-encumbered feet.
Robert C. Sands.
As the basaltic trap-rock is one of the oldest geological[page 53] formations, we might still appropriately style the Palisades "a chip of the old block." They separate the valley of the Hudson from the valley of the Hackensack. The Hackensack rises in Rockland Lake opposite Sing Sing, within two or three hundred yards of the Hudson, and the rivers flow thirty miles side by side. Some geologists think that originally they were one river, but they are now separated from each other by a wall more substantial than even the 2,000 mile structure of the "Heathen Chinee."
It might also be interesting to note Prof. Newberry's idea that in pre-glacial times this part of the continent was several hundred feet higher than at present, and that the Hudson was a very rapid stream and much larger than now, draining as it did the Great Lakes: that the St. Lawrence found its way through the Hudson Channel following pretty nearly the line of the present Mohawk, and the great river emptied into the Atlantic some 80 miles south of Staten Island. This idea is confirmed by the soundings of the coast survey which discover the ancient page of the Hudson as here indicated on the floor of the sea far out where the ocean is 500 feet in depth. A speculation of what a voyager a few million years ago would have then seen might, however, as Hamlet observes, be "to consider somewhat too curiously" for ordinary up-to-date tourists. But even, granting all this to be true, the Palisades were already old, thrown up long ages before, between a rift in the earth's surface, where it cooled in columnar form. The rocky mould which held it, being of softer material, finally disintegrated and crumbled away, leaving the cliff with its peculiar perpendicular formation.
A recent writer has said: "The Palisades are among the wonders of the world. Only three other places equal them in importance, but each of the four is different from the others, and the Palisades are unique. The Giant's Causeway on the north coast of Ireland, and the[page 54] cliffs at Kawaddy in India, are thought by many to have been the result of the same upheaval of nature as the Palisades; but the Hudson rocks seem to have preserved their entirety—to have come up in a body, as it were—while the Giant's Causeway owes its celebrity to the ruined state in which the Titanic forces of nature have left it. The third wonder is at Staffa, in Scotland, where the rocks have been thrown into such a position as to justify the name of Fingal's Cave, which they bear, and which was bestowed on them in the olden times before Scottish history began to be written. It is singular how many of the names which dignify, or designate, favorite spots of the Giant's Causeway have been duplicated in the Palisades. Among the Hudson rocks are several 'Lady's Chairs,' 'Lover's Leaps,' 'Devil's Toothpicks,' 'Devil's Pulpits,' and, in many spots on the water's edge, especially those most openly exposed to the weather, we see exactly the same conformations which excite admiration and wonder in the Irish rocks."
Where the mighty cliffs look upward in their glory and their glow
I see a wondrous river in its beauty southward flow.
